How to Remove All Whitespace Characters from a String in Rust - Step by Step Examples

How to Remove All Whitespace Characters from a String in Rust ?

Answer

To remove all whitespace characters from a string in Rust, you can use the `chars` method to iterate through characters and filter out whitespace characters.

✐ Examples

1 Remove Whitespace from "Hello World"

In this example,

We create a string str with a value of "Hello World".
We iterate through each character using the chars method and filter out whitespace characters.
Finally, we collect the non-whitespace characters and join them into a string modified_str.
We print the modified string modified_str.

Rust Program

fn main() {
    let str = "Hello World";
    let modified_str: String = str.chars()
        .filter(|&c| !c.is_whitespace())
        .collect();
    println!("Modified string: {}", modified_str);
}

Output

Modified string: HelloWorld

2 Remove Whitespace from "apple\tbanana\n cherry "

In this example,

We create a string str with a value of "apple\tbanana\n cherry ".
We iterate through each character using the chars method and filter out whitespace characters.
Finally, we collect the non-whitespace characters and join them into a string modified_str.
We print the modified string modified_str.

Rust Program

fn main() {
    let str = "apple\tbanana\n cherry  ";
    let modified_str: String = str.chars()
        .filter(|&c| !c.is_whitespace())
        .collect();
    println!("Modified string: {}", modified_str);
}

Output

Modified string: applebananacherry
